Title: Replay Gain on very large collection
Post by: Juice on February 21, 2003, 08:20:17 am
?
Hello all, have enjoyed reading the posts, now I have a question:

I would like to gain level all of my music and have a very large collection (27,000 +). I was wondering if someone had a guess as to how long this would take, is there a formula?

Also, will this actually change my MP3 files or is this info stored in the MJ databse?

Loving this product... have tried all players/Jukeboxes on the market (MM, Media Player, Muzicman...).

Cheers

Hi 27000+,

When King says "A long time" he really means it ! ;)

Well, from my experience and depending on the average length of songs and of the speed of your CPU, expect something around 10-20 secs / tracks average, that's about 3 to 4 tracks / mn and ~200 tracks/hour.

So, yes, for 27000 tracks it will take something like 130 hours (5 days) on a sytem like mine (Athlon 1.2Ghz)

Do 2000-3000 tracks every night  for two weeks !

To have a more precise figure, setup a playlist of a hundred tracks, with a good assortments of typcal lengths from your main lib. Analyze and time it, that'll give you a better figure for your own system.

Good luck !

Christian

Thanks Christian!

Your answer was a little clearer than KingSparta's.  ;)

Could someone (You can have another shot KingSparta) let me know if this will actually change my MP3 files or is the gain settings info stored in the MJ databse?

Thanks for your time, a helpful forum is very often the key to a good -vs- great product.

Thanks.....

I forgot to say,

Audio analysis will not change your mp3. The calculated values are stored in the database and optionaly stored in the ID3V2 tag.

It doesn't change the music data itself...just adds a few xtra tags with the recommended dB gain values.

10-27

I would say 5 days AND the week-end.......
Because sometimes ,MC just close himsef when you are sure it is working hard.
Not so important because you have the case  'Skip Analyzed files'

But it would take a lot of time to load first the Audio analyse window ,second the starting of replay gain if the program needs to go throught the 27000 songs first and few thousands analysed files after  before starting.
If for now you do not put more music on your drive ,just do as i did: A-B-C-D ect ect.
One or two or more letters at once.
Like it you know -more or less - where you are

Your in good hands.

I was going to figure it out but i am not home to do a test, and i could have did a calculation for you.

I don't have MC9 here at work to do the test.

LIVE FROM TEL_AVIV=====
10 minutes = 48 songs.
Any kind of rock music.
if you have only punk songs it would be faster
if you have s-h-ity pink floyd look a like music you would need MUCH more time

So King's answer was VERY accurate


King: i analyse all the rips i did to upload to YADB tracs infos to see my fastest  BPM.
Until now ,no more than 155...not me the winner
